BACKGROUND

Lighting elements often are used to illuminate a variety of consumer products, including wearable accessories, novelty items, or the like. Existing illuminated products, however, are generally only capable of exhibiting fixed illumination with one or more light sources. An existing wearable accessory, for example, might utilize a single white-light bulb as an illumination source, with the white-light shining through a transparent colored material. Such accessories only exhibit an illumination of a single type (a function of the color of the transparent material) or at best, by varying the intensity of the bulb output, a single-colored illumination with some range of controllable brightness. Other existing systems, to provide a wider range of colored illumination, may utilize a combination of differently colored bulbs. Such accessories, however, remain limited to a small number of different colored states.

The light system 100 can be coupled with a sensor to sense an environmental condition and to display illumination that indicates the condition. For example, an oven can light in a red color if it is hot. Sensor and feedback applications are described more particularly in certain patents and patent applications incorporated by reference herein.

In yet another embodiment of the present invention, an illumination system is disposed in combination with a scent-producing facility. Together with a processor or processors, this combination allows simultaneous or coordinated production of controlled scent and illumination. In embodiments, the scent/illumination device can be employed in conjunction with a network. In embodiments, the device may be provided with addressable control facilities. In embodiments, the devices can be employed using data delivery protocols such as DMX and power protocols such as pulse width modulation. In embodiments, the devices may be equipped with a communications facility, such as a transmitter, receiver, transceiver, wireless communications facility, wire, cable, or connector. Thus, the device can store, manipulate and otherwise handle data, including instructions that facilitate controlled illumination or controlled scent, or both. The device may also, in embodiments, receive control signals from another source, such as a user interface, an external computer, a sensor, or the like.

A wide variety of illumination and display effects can be employed in connection with the scent producing facility, ranging from color washes, to rainbow effects, to rapid changes in color, and the like. The scents can also be controlled whereby different chemicals are triggered to respond to an input signal (e.g. Digiscents Inc. multi-scent devices) and a ‘smell wash’ or smell sequence synchronous with a color wash or color sequence can be activated.

In other embodiments, the illumination can reflect a sensed condition, such as a condition sensed in the environment of the scent-producing facility. In other embodiments, the illumination can reflect a condition of the scent-producing facility, such as remaining life of the device, the remaining amount of scent-producing materials or chemicals, the quality of the scent, the strength of scent, battery life, or the like.

The scent-producing facility may be an air freshener or other scent-producing facility that may optionally plug into a room outlet. In embodiments, the scent may be varied in response to data received by the device, as controlled by a processor that also controls the illumination.

The scent-producing facility can be programmed to produce scents in concert with the illumination; thus, a scent may be correlated with illumination that reflects a similar aesthetic condition, emotional state, environmental condition, data item, or other object or characteristic. For example, a pine scent could be coupled with green illumination, while a pumpkin scent could be coupled with orange illumination. Thus, a wide range of correlated colors and scents can be provided in a device where one or more processors controls both scent and illumination.

In an embodiment, the device is a combined air freshener and color-changing night-light, with a processor for control of the illumination condition of the night light, and with LEDs providing the source of illumination for the night light.

In an embodiment, a gel may be presented and a color changing illumination system may be directed to illuminate the gel. For example, there are many fragrances, deodorants, and the like that are made into gels. This gel can be made into most any shape and an illumination system may be used to project light through the gel. In an embodiment, the gel may appear to be glowing in colors.

In an embodiment, the gel or other material may evaporate over time and as the material evaporates, the light levels captured by the material may diminish. This will result in the light levels decreasing as the material evaporates giving an indication of material life. In an embodiment, the light may actually appear when the evaporation, or other process, has removed a portion of the material.

In an embodiment, the illumination may be associated with a sensor. Such a sensor may measure or indicate germ, bacteria or other contamination levels and cause an illumination system to emit certain lighting conditions. An embodiment may be a color changing “germ alert sensors” that would hang in the toilet or trashcan, etc. Example: as your tidy bowl reached the terrifying point of not flooding the sewer lines with chlorine at every flush, your tiny tricolor LED would pulse RED hues to alert you.

Another aspect of the present invention is providing light from an apparatus that is coordinated with a scent generation portion of the apparatus. For example, the apparatus may be a plug-in style air freshener and the light produced by the air freshener may be colored to coordinate with the type of scent being emitted. The light emitted from an evergreen scented air freshener may be greenish blue for example. Another aspect of the present invention is providing an indication of useful life of a portion of a system. The system, an air freshening system for example, may have a life limited air cartridge and an indication of life may be provided. The indication of life may be provided through a certain lighting pattern for example.

An embodiment of the present invention is a scent producing apparatus 1900 with an illumination source 100. One such device is illustrated in FIG. 19. The illumination source, or system, may be similar to that described above as illumination system 100. The illumination system 100 may be arranged to produce color controllable illumination through an optic 1908 for example. The scent producing apparatus 1900 may be adapted to plug into a conventional wall power outlet through an adapter 1910. The apparatus 1900 may include a vented portion 1914 to facilitate the emission of scent from a scent cartridge 1902 once installed.

According to one aspect of the invention, the scent producing apparatus 1900 may be adapted to read, or otherwise identify, certain characteristics of the scent cartridge. For example, it may identify the type of cartridge, the scent to be produced by the cartridge, the date of manufacture, date of installation, serial number or other parameter. In an embodiment, the scent producing apparatus may be adapted to alter the color, pattern, intensity or other parameter of the light emitted by the illumination system 100. For example, the cartridge 1902 may be encoded to identify the type of scent it produces. The scent producing apparatus 1900 may read the code and alter the light it produces to match the type of scent. The scent may be deemed an evergreen scent and the light emitted from the illumination system 100 may be altered to be green or blue for example. The light may also have a temporal effect such as to alternate between a green and blue or generate some other pattern intended to coordinate with the scent.

In another embodiment, the scent producing apparatus 1900 may also monitor the duration the cartridge 1902 is in the scent producing apparatus 1900 or otherwise monitor the effectiveness of the cartridge. Once the effectiveness, or lapsed time, indicates the cartridge should be changed, the illumination system 100 may be adapted to change the lighting pattern, color, intensity or other parameter it is producing. This method of operation may be useful indicating to a user that the cartridge is due to be changed. In an embodiment, the apparatus 1900 may include a user interface 1912, much like the user interface identified above. The user interface 1912 may be used to override the indication light to provide normal illumination or alter the illumination to accommodate his/her desires. In an embodiment, the illumination system 100 may be adapted to stay in an override operation mode for a preset period of time. For example, the preset period may be three days, such that the light stays in the override lighting pattern for three days and then automatically converts back to the end of usefulness indication. This may be useful to allow a user to go into an override mode for a period of time but automatically be reminded that the cartridge needs to be renewed. In an embodiment, the user may set the time of the override and/or the user may have the option of electing an override period that does not automatically end.

In an embodiment, the apparatus 1900 may have a set of contacts 1920. The contacts 1920 may be associated with a processor in the apparatus 1900 (e.g. processor 104 of the illumination system 100). The processor 104 may be adapted to monitor the contacts 1920 for activity or association characteristics with a cartridge 1902. For example, the contacts 1920 may be on a rear interior wall of the apparatus 1900 and the cartridge 1902 may have conductive strips 2002 on the rear wall 1904 of the cartridge 1902. The illustrations in FIGS. 20A and B show different patterns of conductive strips 2002 on the rear wall 1904 of the cartridge 1902. The illustration in FIG. 20A may represent the conductive strip pattern associated with an evergreen scent cartridge while the illustration in FIG. 20B may represent a raspberry scent cartridge. When a cartridge 1902 with the pattern 2002 of FIG. 20A is inserted into the apparatus 1900, the contacts 1920 will sense the pattern and the processor 104 can adjust the color of the light emitted accordingly. For example, the bottom protrusion of pattern 2002 may be aligned with one of the contacts 1920 in an array of contacts and the upper protrusion of pattern 2002 may be associated with another contact 1920 of the array. Depending on the placement of the upper pattern, for example, may dictate which contact in the array is associated with the pattern. The processor 104 may then recognize the pattern and adjust the lighting accordingly. This is but one example of a system designed to recognize a cartridge type of many that are envisioned by the applicant and encompassed by the present invention. For example, FIG. 20C illustrates another such method.

FIG. 20C illustrates the rear wall 1904 of a cartridge 1902. The rear wall 1904 may include three electrically conductive pads. Pads 2004 may be designed to bring power to a circuit on the cartridge 1902 and the third pad 2010 may be a data pad for the circuit. These three pads may be associated with a circuit (e.g. integrated circuit 2008) and the integrated circuit may be adapted to output data to the data pad, which in turn may be associated with the processor 104 in the apparatus 1900. The integrated circuit may be adapted to produce data indicative of the cartridge type, scent, manufacturing date, installation date, lapsed time that the cartridge received power (e.g. measure of time in use), or other parameter. The circuit may include a counter and once the counter reaches a particular point it may indicate it is time to change the cartridge through a display of a certain lighting pattern, or it may make a sound or provide some other type of alert. The timing system may provide several indications of remaining usefulness so the user can become informed as to the state (e.g. the cartridge is 80% spent) and time the replacement accordingly.

In an embodiment, the apparatus 1900 may be programmed to display a color of light that is an indication of useful remaining life of the cartridge. For example, the light may be blue when the cartridge is new or full and it may gradually, or in some other predetermined way, change through a rainbow of colors until it reaches red where red indicates the cartridge has reached the end of its useful life. The user interface 1912 may allow a user to select such a mode, for example.

In an embodiment, the apparatus 1900 may include a switch 1918 where the switch 1918 is depressed, or otherwise activated, when the cartridge 1902 is loaded into the apparatus. The processor 104 may monitor the activation of the switch 1918 as an indication of the cartridge 1902 being loaded. From this indication, the apparatus 1900 may monitor or predict certain events. For example, the processor 104 may begin a timing circuit in an effort to predict the useful life of the cartridge 1902. In an embodiment, the switch may be associated with a mechanism or circuit to indicate whether the cartridge has been removed during a power down cycle. For example, the switch may be associated with a dial where the position of the dial can be read. When the apparatus 1900 is re-powered, the processor 104 may check the dial position and compare to the position indication of the dial before power-down to indicate if the cartridge has been removed. If the cartridge was removed, the processor may automatically start a new timer for the prediction of cartridge life expectancy. In an embodiment, the processor may also provide an indication (e.g. certain lighting pattern) that it believes the cartridge has been changed and ask for a user confirmation through the user interface 1912.

While the invention has been described in connection with certain preferred embodiments, other embodiments will be readily understood by those of ordinary skill in the art and are encompassed herein.
